Revolutionary Sustainable Design: 100M Green Hostel in Barcelona

The 100M GREEN HOSTEL in Barcelona is a revolutionary building that embodies the principles of eco-tourism and sustainable living. With a zero carbon footprint, the hostel is self-sufficient in terms of energy consumption and independent in food production, water consumption, and waste disposal. This landmark structure seamlessly integrates urban functions with nature, offering a unique experience for young travelers.

The hostel's design is truly remarkable. Developed from a rectangular plan mesh, the building gradually tapers upwards, resembling a sparkling blade rising above the city. Its distinctive form immediately captures attention, and the vibrant, green interiors offer breathtaking views of Barcelona through numerous passages.

The hostel is encased in a mesh grid oriented at forty-five degrees, which provides shade and supports a green wall during the summer season. The predominantly glass facade, with varying opacity and colors, allows outsiders to glimpse the building's internal structure. This transparency creates a sense of connection between the hostel and its surroundings.

Functionally, the hostel is divided into four areas at different levels. The tower basement houses a pub/bar and market stands, which are accessible from the plaza and connected to the vibrant nightlife of the MACBA square. The ground floor remains lively and bustling with retail activities. The central core contains the main collective functions, with open spaces and floating rooms. The kitchen is conveniently located near the green cultivated areas, allowing guests to enjoy fresh, locally sourced food. The dining room spans two floors and offers a terrace overlooking MACBA square, where guests can dine outdoors while enjoying the lively atmosphere. Additionally, a south-facing terrace provides stunning views of the sea.

The ten floors above house the hostel's rooms, each with its own south-facing balcony. The rooms are accessible through a balcony that overlooks a full-height courtyard. On the north side, cultivated terraces enhance the natural beauty of the area. Finally, at the top of the building, a viewing area offers a breathtaking 360-degree view of the city. Guests can also relax in the lounge, savoring a cocktail while browsing the local products and hotel gadgets available for purchase.

The orientation of the building maximizes the use of sunlight, allowing for natural heating during winter months and efficient shading during hot summers. The south wall, made of greenhouse glass, harnesses the sun's warmth, while the thick walls of the rooms store heat, providing natural heating during the night. The north courtyard promotes air circulation and ventilation, enhancing cooling during summer months. The hostel's green vertical side acts as a shade during summer, further enhancing energy efficiency.

The 100M GREEN HOSTEL is a testament to sustainable architecture and eco-friendly living. It seamlessly blends urban functions with nature, providing an unforgettable experience for young travelers seeking to explore Barcelona while minimizing their environmental impact. This landmark building sets a new standard for eco-tourism and represents Barcelona's commitment to a greener future.
